Limit Cycles Bifurcating from an Invisible Fold–Fold in Planar Piecewise Hamiltonian Systems
(2020-01-01)
The aim of this article is twofold. Firstly, we study the existence of limit cycles in a family of piecewise smooth vector fields corresponding to an unfolding of an invisible fold–fold singularity. More precisely, given ...
Turbine wake sensitivity to different atmospheric stabilities
(Servicio Meteorológico Nacional., 2018)
Chromosomal size conservation through the cell cycle supports karyotype stability in Trypanosoma cruzi
(ELSEVIER SCIENCE BV, 2007-05)
The Trypanosoma cruzi karyotype shows an extensive
chromosomal size polymorphism. Absence of condensed mitotic
chromosomes and chromatin fragility are characteristic
features of T. cruzi which would allow DNA breaks and ...
Immobilization and stabilization of an endoxylanase from Bacillus subtilis (XynA) for xylooligosaccharides (XOs) production
(2016-01-01)
Xylooligosaccharides (XOs) are small oligomers constituted by 2-10 units of xylan monomers, with important nutraceutical properties. They can be produced through hydrolysis of xylan catalyzed by an endoxylanase. The use ...
Deciphering the role of the electrostatic interactions in the alpha-tropomyosin head-to-tail complex
(WILEY-LISS, 2008)
Skeletal alpha-tropomyosin (Tm) is a dimeric coiled-coil protein that forms linear assemblies under low ionic strength conditions in vitro through head-to-tail interactions. A previously published NMR structure of the Tin ...
